i cant start this thing without using starting fluid and i dont want to keep on doing that.and the other problem is when i do get it to fire up it revs way up and stays up and i cant get it to come back down.it smokes real bad on the left cylinder but is probably right on the right cylinder. i rebuild carburetors all the time but none have the stupid tors on them.BTW i still got tors. how do you adjust the idle on it?bone stock, theres a K&N filter, and im at sea level. i just fired it up for the first time yesterday and the carbs probably arent synced. i wouldnt even know where to start. help me out!!!!
